We’re excited to announce the release of jQuery UI v1.7, the newest version of jQuery’s effects and UI library. This release culminates many months of development in which a major overhaul of the whole library was performed and a new CSS framework introduced, all in order to provide a professional and easily extensible set of UI controls and effects for jQuery developers. The new CSS framework is especially exciting since it will not only allow for easy theming of jQuery UI controls but also allow plugin authors in general to take advantage of ThemeRoller, the dynamic theme generation application developed by the Filament Group for the jQuery UI project.
